Description

A kind of analog channel measurement method and base station
Technical field
The present invention relates to field of communication technology more particularly to a kind of analog channel measurement method and base stations.
Background technique
In view of multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) technology for improving peak value The important function of rate and system spectrum utilization rate, the evolution of long term evolution (Long Term Evolution, LTE)/LTE It (LTE-Advanced) etc. is all with MIMO+ orthogonal frequency division multiplexing (Orthogonal in wireless access technologys standard Frequency Division Multiplexing, OFDM) construct based on technology.The performance gain of MIMO technology Spatial degrees of freedom can be obtained from multiaerial system, bigger data is obtained using spatial degrees of freedom and transmits, therefore, MIMO A most important evolution tendency of the technology in standardisation process is the extension of dimension.
In LTE Rel-8,4 layers of MIMO transmission can be at most supported.Rel-9 emphasis to multi-user (Multi-User, MU)-MIMO technology is enhanced, and at most may be used in the MU-MIMO transmission of transmission mode (Transmission Mode, TM) -8 To support 4 downlink data layers.Rel-10 then passes through 8 port channel state information reference signals (Channel State Information-Reference Signal, CSI-RS), terminal-specific reference signal (UE-specific Reference Signal, URS；UE, User Equipment) with the introducing of multi-granule code book further improve the sky of channel state information Between resolution ratio, and the transmittability of SU-MIMO is further extended into most 8 data Layers.
In base station antenna system using traditional passive antenna system (Passive Antenna System, PAS) structure, Mutiple antennas port levels arrangement, wherein each antenna port corresponds to independent radio frequency-intermediate frequency-Baseband Channel, and each day It is connected between multiple a period of time of the corresponding vertical dimension of line end mouth by radio-frequency cable.Therefore existing MIMO technology can only be tieed up in level It is realized to each terminal signaling by the adjustment between the relative amplitude different port and/or phase in horizontal dimension space characteristic Optimization, can only then use unified sector-level figuration in vertical dimension.Active antenna system (Active is introduced in mobile communication system Antenna System, AAS) after technology, base station antenna system can obtain bigger freedom degree in vertical dimension, can be three Dimension space, which is realized, optimizes UE grades of signal.
Industrial circle further promotes MIMO technology towards the direction of three dimensional stress and large-scale at present.3GPP is just It is estimated thereafter also to carry on 8 antenna ports and vertical beam below tax in the research project for carrying out 3D Channel Modeling The full dimension MIMO (Full of shape (elevation Beamforming, EBF) and more than 8 ports (such as 16,32 or 64) Dimension MIMO, FD-MIMO) technical research and standardization effort.And then more prediction ground has been carried out for base for academia In the research and test job of the MIMO technology of more large-scale antenna array (including 100 or hundreds of even more a period of time).It learns Art research and preliminary channel the result of actual measurement shows that, extensive (Massive) MIMO technology being capable of greatly lifting system frequency band Utilization efficiency supports greater amount of accessing user.Therefore massive MIMO technology is considered as next by major research tissue One of most potential physical-layer techniques in Generation Mobile Communication System.
Massive MIMO technology is needed using large-scale antenna array.Maximum may be implemented although with total word array The spatial resolution of change and optimal MU-MIMO performance, but this structure needs a large amount of modulus (AD)/digital-to-analogue (DA) conversion Device and radio frequency-Base-Band Processing channel, either equipment cost or Base-Band Processing complexity all will be huge burdens.This One problem seems especially prominent in high band, big bandwidth.In order to reduce the cost of implementation and equipment of massive MIMO technology Complexity, in recent years it has been proposed that using numerical model analysis beamforming technique.
As shown in Figure 1, so-called numerical model analysis wave beam forming, refers on the basis of digital beam forming (DBF), close Increase level-one wave beam forming, i.e. analog beam figuration (ABF) in the radiofrequency signal of antenna system front end.Analog beam figuration can By relatively simple mode, makes to send signal and channel realizes more rough matching.Formed after analog beam figuration etc. The dimension for imitating digital channel is less than actual antenna amount, can substantially reduce ad/da converter part, digital channel number and phase The Base-Band Processing complexity answered.The interference of analog beam figuration remnants can be handled in numeric field, to guarantee MU-MIMO The quality of transmission.
For digital wave beam forming, numerical model analysis wave beam forming is the half-way house of performance and complexity, Practical prospect with higher in the big bandwidth of high band or the very big system of antenna amount.
In MIMO technology, especially for MU-MIMO technology, the precision for the channel state information that network side obtains is direct The efficiency for determining precoding/wave beam forming precision and dispatching algorithm, to influence overall system performance.Therefore, channel shape The acquisition of state information is one of problem most crucial in MIMO technology standardization.
According to current LTE signal structure, channel estimation can be carried out according to the reference signal in baseband signal and obtain number Channel status needed for word wave beam forming.Lead to since multiple analog channels of analog beam figuration part are equivalent to a number Road carries out the channel matrix that digital channel estimation obtains by reference to signal so that digital channel number is less than actual antennas number Dimension is well below the dimension of antenna end channel matrix, therefore analog beam figuration part can not directly be obtained using numeric field The channel state information obtained.Also, due to reference signal be it is corresponding with digital channel, it is logical in the number and number of analog channel In the case that the number in road is inconsistent, the channel state information of analog channel directly can not be obtained according to reference signal measurement.

Step 404: base station determines frequency range belonging to the frequency of transmitting uplink reference signal use, from the simulation of selection Analog channel group corresponding with the frequency range is selected in the group subset of channel, using reference signal to the analog channel group of selection It measures, other analog channels in addition to the analog channel for including in the analog channel group in measurement except selection keep closing It closes；
Step 405: base station judge measurement accuracy whether meet demand, alternatively, judging whether to meet n × Nf× M is equal to Nt, If satisfied, then exporting n × NfThe measured value of × M analog channel, analog channel measurement process terminate；Otherwise, step is executed 406；
Step 406: base station updates n=n+1, turns to go to execute step 402.
Wherein, base station received reference signal on same time resource can be used to measure simultaneously corresponding different frequency Analog channel in the analog channel group of range can measure multiple simulations of corresponding different frequency range in the same time Channel group, so that the analog channel in multiple analog channel groups can be measured simultaneously, the time needed for shortening measurement.
